2. IDE connectors (40-1 pin PRI_IDE, SEC_IDE)
The onboard IDE connectors are for Ultra DMA 133/100/66 signal cables.
There are three connectors on each Ultra DMA 133/100/66 signal cable:
blue, black, and gray. Connect the blue connector to the motherboard’s
IDE connector, then select one of the following modes to configure your
device(s).
• Pin 20 on the IDE connector is removed to match the covered hole on
the Ultra DMA cable connector. This prevents incorrect insertion when
you connect the IDE cable.
• Use the 80-conductor IDE cable for Ultra DMA 133/100/66 IDE devices.
